About this map

The Owyhee River meanders through this remote portion of Malheur County, carving a path past the prominent Lambert Rocks and the dramatic geological formations of Chalk Basin. This high desert landscape is defined by its water management, evidenced by numerous man-made catchments like Morcom Reservoir Number Two, Anawalt Reservoir, and White Wash Reservoir. These features, along with Sand Spring, illustrate the critical importance of water resources for cattle ranching in the Oregon backcountry.

Evidence of human habitation and logistics is concentrated around the Bogus Ranch at the base of Bogus Rim. The area's limited road network, including Bogus Ranch Rd and Airstrip Rd, highlights the isolation of these outposts. Smaller seasonal watercourses such as Ryegrass Creek, White Rock Creek, and Bogus Creek feed into the river system, supporting the sparse vegetation and livestock operations characteristic of this arid region in the early 21st century.
